Abstract
The present invention relates to a method for soft switch attendant console maintaining and recovering, which comprises that step 1, a soft switch attendant console server applies service data points for reproducing to a soft switch device; step 2, the soft switch attendant console server requests the soft switch device the service data points for reproducing to reproduce; step 3, the soft switch attendant console server changes the distant end media of the user to the service data points for reproducing; step 4, the soft switch attendant console server requests the soft switch device to free up the service data points for reproducing; step 5, the soft switch attendant console server changes the distant end media of the user to a media for the soft switch attendant console calling. On the basis of the exiting soft switch device and the gateway device, the present invention fully used the existing resources, and realizes the soft switch attendant console maintaining and recovering through the SIP signaling message interactive flow.
Description
Technical field
The present invention relates to soft switch traffic console, relate in particular to the method and system that a kind of soft switch traffic console keeps, recovers.
Background technology
The realization flow that keeps in the prior art and recover is roughly as follows:
If soft switch traffic console A and B conversation, the party A-subscriber will keep the party B-subscriber, the A side directly sends INVITE to the B side by SIP (SIP) signaling, information Connection Information field IP address, service data point in the INVITE (SDP) is 0.0.0.0, media mode is sendonly, the B end carries out medium to B and switches when receiving this message, the distant end media of switching B is the medium in the INVITE, return 200 OK message for behind the handover success A side, carry party B-subscriber's user media in this 200 OK message, answer ACK confirmed after A received acknowledge message 200 OK, thereby B is kept; When the party A-subscriber will recover to converse with B, the A side sends INVITE to the B side, SDP information in this INVITE is the conversation medium of A, the B side is carried out the medium switching to B after receiving this message, the distant end media of switching B is the conversation medium of A, return 200 OK message for then the A side and bring A side with the user media of B, the A side is returned ACK and is confirmed, realizes recovering thereby reenter conversation.
Though the maintenance flow process of above-mentioned implementation is simple, the maintenance sound of playing is a maintenance sound the most basic on B side gateway or the media server, and this keeps sound too simple, can't realize keeping the personalized and diversified of sound.Development along with business, the maintenance sound that may need customized personal on the console, wish that such as certain mechanism it is the introduction of our company that this mechanism console keeps sound, to make full use of the time value with user's communication, if use above-mentioned maintenance, the implementation of recovery, can't satisfy the needs of this business development.
